    PID Tuning

    Hey my existing propportional gain the automatically set value is 2.0 integral 20ms but I have tried a thousand variations of these values and still cant seem to get a steady output.

    PID Tuning

    I am trying to tune a PID controller to control a motor via a variable speed drive. The vsd used is a siemens micromaster 410 and ramp up and down times are low (1.5). I cant seem to get the speed output to remain steady. When in manual mode it produces a perfect steady output but in automatic...

    Encoder Position Step 7

    first time user here so go easy on me. The encoder is an siemens incremental encoder but it is the PLC program that is the problem however I think I have it sorted now. I will know for sure tomorrow when I return to my PLC however my SFC program is press start button motor comes on at set...

    Step 7 - Encoder

    Hi I am trying to control the position of an encoder using step 7. I want the position to change when the set point demands it so if position 1 is 10 and position 2 is -10 this would activate a change? I tried using a comparator block but if the tird position is -20 this activates a change...

    Scada Recipe Function

    Hi I am doing a project where I control a motor using siemens plc, vsd and scada wincc. I want to have 3 different sequences and using the Scada recipe function call sequence 1, sequence 2 and sequence 3 at different times etc. how can I do this using the recipe function? I have the sequences...
